To all whom t may concern Be lit known that I. ROBERT D. LOOSE, a citizen of the United/States, and a resident of the city of Fort lVorth, in the county of Tarrant and State of rfexas, have invented a certain new and useful Improvement in `Attachments for Carbureters; 'and I do I peculiar combination of parts and details of construction, as hereinafter 'first fully s et forth and described and then pointed out in the claims.

The essence of my invention resides in I providing the outlet portion of a carbureter for a ,hydro-carbon engine with means, whereby there is induced a vortical whirl to the volatilized gases passing from said.

carbureter. And correlated therewith are other means whereby the' passage of said gases through the outlet portion of said carbureter, mayv be estopped entirely, or reduced in volume to any desired degree.

Briefiy speaking, the outlet portion of my carbureter is possesse of a plurality of heli cal vanes on the interior thereof imparting the vortical whirl or movement to the volatilized mixture passing therethrough. And located between adjacent vanes areprovided means whereby the mixture may be entirely estopped from passing through the helical channels produced by said vanes; or said means may be so adjusted as to attenuate the flow of the mixture through the channels between the adjacent helical vanes as hereinafter described.

In the drawing Ialready referred to, which serves to .illustrate my said invention more fully, Figure 1 is a plan section of my device, the same being taken in line l-l of Fig. Q and showing the means for closing the channels between the helical vanes in closed position. Fig. 2 is a longitudinal vertical section of a separate shell in which my invention is embodied` the said section being taken in line 2-9. of Fig. l, and likewise designating said channels as being closed /by said closing means. Fig. 3 is a plan sec tion similar to that of Fig. I, but showing V/the channel closing media in a partially Open position to permit an attenuated flow of vvola-tilized mixture therethrough. Fig. 4 isna vertical section in line H of Fig. 8. Fig. 5 is an elevation of the upper portion of a typical carbureter, within which is 'incorporated my invention. i

Like parts are'indicated by corresponding symbols or characters of reference in all the figures of the drawing.

It is wel'l known that in the volatilization of a liquid hydro-carbon as t/akes place in the carbureter of an engine of the class de scribed, 'there are a plurality of hydro-carbon molecules which pass through the carbureter in a liquid state. and it is to the end of breaking up these molecules and insuring a more thorough mixture that my device is produced. l

Referring now te the drawing. A designates the upper portion of the shell of a carbureter. as seen in Figs. 4 and 5, while A', Fig. 2. indicates a separate shell adapted to be introduced between a typical type of carbureter and the intake manifold of a motor, so that/my invention may be installed in power plants now in operation.

In the case of my device being` incorporated as a part of a carbureter, B is the flange thereof adapted to/mate or match with a like flange (not shown) upon the lower .end of an intake pipe of .a motor of the character specified, the bolt holes C being provided whereby the carbureter may be fixed in position to said flange of said intake pipe. On the other hand, if my device be constituted as a separate structure, then there is formed on the lower end of the shell A', Fig. Q, a flange 50. In this instance, this flange 50 will connect with a like flange (not shown) on the carbureter, and the flange B will connect with the intake manifold as aiready described. In either structure the essentials of my invention are precisely the ame.

The shell A is annular in plan, as seen in the drawing and the usual butterfly or other throttle, valve is dispensed with. Instead, however, there are provided or integrally formed within said shell a plurality of vertical helical vanes l0. spaced equidistantly apartwithin the shell A, the inner edges of said vanes abutting, or formed integral with an axial upstanding post 11, whieh is of preferably square cross section as will hereinafter more fully appear. A\.nd it is now to he stated that the upper edges of the varies l() are preferably fared in a vertical plane so that the same present in plan a single line 1;) as seen in l1`igs, 1 and Il. Pivoted for oscillation in the interior of 'the salate-hell A' preferably at the upper ends ot the vanes lll are a plurality ot diaifhrag'fins 13. the same having their outer routeurs il titting the limer eontour of the shell A and their inner eontours abutting the respective faces of the upstanding post l1. These diaphragms are substantially triangular in shape with the base and altitudinal tdges l5 and 15a. as it were, abutting against the upper perpendicular edge of one of the `Janes lll. and the other edge 15"- heing beveled ott' upon its under side. to lie upon the upper edge of the next sueeeeding vv\ane 1u. as seen in Figs. l and 2. so that the said diaphragms and upper edges present a plane surface when the diaphragms are in horizontal or elosed position to estop the passage of volatile mattei' through the ebannels formed by the vanes 1t).

iledially of the areuate length ot' the outer edges ll of the diaphragms lil are tia'odueed bossesy or protube inees 163 whieh are internally apertured for jte reeeption of studs-li. These studs 1T are pinned fast to said diaphragms and extend radially through the shell -t as elearly seen in the drawing. and. on the exterior of said shell. are possessed of depending leversl 1S. whieh are likewise pinned or otherwise fixed to said studs. The said levers have their lower ends lt areuate. said ares having their renters eoineident with the axes of the studs iT: and. on the peripheries of said areuate ends 19 are eut or otherwise formed. spur or gear teeth it). eoaeting with like teeth '21 paodueed at intervals in the upper edge of an annular band 22 enibraeing the exterior of the shell A and partially rotatable therearouiid. This band preferably made in two halves and lioined together by screws lil passing through ears lon the halves to faeilitate plaeing .said band in position while assembling the parts. To maintain l in proper position on said shell there formed a shoulder '3 around the Shell upon wliieh the band rests in an obvious manner. And. it being understood that the plurality of levers` 1S having their vteeth 20 in mesh with the teeth 2l of the band 22 up or down movement of said band is prevented. A\ttention is now directed to the fact that the number of teeth on each lever eorresi'ionds with the number of teeth on the band with which that particular lever eoaets, and the number of Such teeth is so arranged that when the last tooth of eaeh of the levers engages the last tooth of eaeh set on the band through the partial rotation of the said band. the diaphragnis lil will have been rotated from a fully closed to a fully open position to permit the full llow of the gases through theI channels formed by the vanesl lll. Further rotation of the diaphragms is prevented by the engagement of studs )t on the.- band :22. against the areuate ends lLl of the leverslv* in a manner readily understood. Projeeting from the band 'J2 is a handle mene her 2T. having a forked end h or like niember for attaehinent of rods or links whereby the band may1 be aetuated 'from a. distance. as for instant-e from the seat of an automobile.

The funrtioning of my deviee as thus far diselosed may now be desrribed as follow-f.j it being understood that the position of the levers 1S as seen in Fig. indieates the elosed position of the diaphragms lil. in whit-h position no gas may pass out of the earbureter to the motor. uit upon movenient of the handle T to the position shown in Fig. il. it will be observed that eaeh of the diaphragms have been slightly tilted. the edges 15 thereof arising from their coat-ting ends of the respeetive vanes 11"), and the opposite edges 17 deseending below the next adjacent vane. as elearly seen in Figs. Il and rl. thereby produeing two openings '.)ll and 30, Fig. il. for eaeh channel. 'l`he uptlouing gas passes through the said ehannels in a vortitfal whirl and strikes the diaphragms. is delleeted thereby and then passes through the said openings Ztl and Slt?. A\s the gas strikes the diaphragms the liquid moleeules are broken up as it were, and by reason of the vortieal action are kneaded and intermingled. and eaused to become a part of the volatilized mixture, thereby produeing a far more hon'iogeneous mass than is possible at the present time. nd l have proved by extended experiments that b v employing the eombination of the helical vanes and the diaphragnis. whieh also aet as baille plates. the mixture iQ raiableA of absorbing or taking up niuh more oxygen than before. and that a slight opening of the diaphragms produees praetirally the same result as a full opening of the usual butterfly type of throttle valve.

ln order to supply the required amount of extra oxygen as above stated. l pierce the walls of the shell directly below the lower ends of the vanes with a plurality ot' openings 31 corresponding in number to the number of vanes. Embracing the exterior of the shell A and adapted to close these openings. is provided an annular split or halved band 32. joined together by screws 33 andears 34 and it is to be noted that said hand rests upon a shoulder 35, surrounding the shell A, to maintain the same at proper la headed screw 40 threaded into any one of the threaded-apertures il in the shellA, This screw 40 acts as a fulcrum for link 37. so that as the band '22 is rotated the band 32 is likewise turned to either open or close the oxygen openings 3l in the shell. And it will be easily understood that the extent of the rotation of the band 3:2 with respect to the band 92 may be varied by entering the fulcrum screw 40 into any one of the openings 41 and thereby changing the lrelative rotation ot the bands and varying the extent of uncovering the oxygen openings 31. In this manner the driver of a car may properly regulate the amount of extra oxygen admitted in a manner that is simplicity itself. Y

Vhile herein I have described, and disclosed the preferred embodiment of my invention, I may make various alterations and changes therein, all of which changes are to be'considered within the scope of my invention under a broad interpretation of the doctrine of equivalents. For instance I may place the closing diaphragms at the lower end of the vanes or within the channels at any point intermediate the lengthl thereof as may be desired.

It is now to be understood that this invention may be embodied in any carbureter now on the market by slightly lengthening the upper portion A of such device and slightly changing the shape thereof to lthat shown in the drawing. My invention may also be applied as a separate entity by providing the same with a flange 50 at its lower end, as seen in Fig. 2, so that the device may be bolted between a carbureter and the intake flange of a motor. This construction will enable the owner of a typical carbureter to remove the throttle valve therefrom, and apply my invention in a manner easily understood.

I have hereinbefore disclosed the preferred mode of practising my invention. but I reserve the right to make such and any changes as might occur to one skilled in the art fto which this invention appertains. or to make any and all such alterations as may be permitted under the doctrine of equivalents.
